Oil Pressure Switch

WARNING: This page is about a different car, the 1990 Acura Legend. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the terminal bolt and the YEL/RED wire from the oil pressure switch. See Fig 1.
  2. There should be continuity between the oil pressure switch positive terminal and the engine (ground) with the engine stopped. There should be no continuity when the engine runs.
  3. If the switch fails to operate, check the engine oil level, then inspect the oil pump and pressure if the oil level is correct.
